I have an older 17 foot fiberglass boat.I dont know much about it except that the registration says is a National.Only markings on the boat are GW on both sides in the back.Tag with serial number says National Boat Works.The GW is the exact same as on all the Grady White boats.Ive looked through all the Grady sites i can and dont see a boat like it.This boat is built for the big lakes.Its nice and wide and deep/.Could this really be a Grady White and how do i find out more info on it?Any help will be appreciated.Don
